CAD systems are usually based on a tensor product representation of free form surfaces. In this case, trimmed patches are used for modeling non rectangular zones. Trimmed patches provide a reasonable solution for the representation of general topologies, provided that the gap between equivalent trimming curves in the euclidean space is small enough. Several commercial CAD systems, however, repr...

A hexagonal patch is a plane graph in which inner faces have length 6, inner vertices have degree 3, and boundary vertices have degree 2 or 3. We consider the following counting problem: given a sequence of twos and threes, how many hexagonal patches exist with this degree sequence along the outer face? This problem is motivated by the study of benzenoid hydrocarbons and fullerenes in computati...

computers are used everywhere from home to work these days, thus the effects on the visual system will be more noticeable every day. problems associated with computer usage are generally known as the computer vision syndrome (cvs).these problems include eye fatigue, irritation ,redness , blurred vision and dry eye. all of these problems have adverse effects on individuals in the long term and r...

eye movement desensitization and reprocessing (emdr) process encompasses several nervous system components such as medulla, pons, midbrain, cerebellum, basal ganglia, parietal, frontal and occipital lobes. the role of eye movement (em) has been documented previously in relation with cognitive processing mechanisms. by emdr we can reach some parts of memory which were inaccessible before and als...

Trichophyton rubrum is an anthropophilic fungi and has recently become the most common and widely distributed dermatophyte, isolated of man. The infection usually present as superficial scaling annular patches, but the lesions may involved the extensive area of skin.  A case of multiple cutaneous lesions due to T.rubrum with scaling annular patches and well marginated in much of the skin and in...

introduction “green infrastructure” is a term that describes the abundance and distribution of natural features providing ecological services necessary for community wellbeing specially in urban areas where these are limited. green infrastructure is increasingly espoused by landscape conservation and metropolitan planning because it is an effective way to surrogate ecological network functions ...

Herein, we present a case of Basal Cell Carcinoma (BCC) in 59-year-old woman. It presented with painless itchy, black, gradually enlarged patches which were easily bled under her left eye since three years ago. Dermatological examination the medial canthus region obtained hyperpigmented plaques (2x0.8x0.1cm) uneven skin texture, irregular borders, and erosion on center lesion. We performed fore...
